James Ryan Nolton is a foreign language teacher from the United States who has lived in China for more than three years. He came to visit friends during Spring Festival and stayed in Beijing during the novel coronavirus outbreak.

Ryan compares several cases of viral outbreaks that have had a large impact around the world in the past century and explains why people are afraid of viruses through comparison of data, prevention and control measures, time and other factors.

Ryan also gives positive examples of patients in makeshift hospitals in Wuhan to demonstrate the difficulties in controlling the epidemic. He claims optimism is the best immunity.

Ryan's parents in the United States were very worried about his safety. While chatting with his parents through video, Ryan found they had many misunderstandings about the epidemic. They also don't know much about China's current situation.

In order to reassure relatives and friends in faraway places, Ryan decided to shoot a short video by himself, record the people's living conditions during the epidemic and show the real situation he saw and felt. It also allows more netizens to make a rational and scientific judgment on the epidemic.
